PROCESS OF PRODUCING COMBUSTIBLE FLUID.

SPECIFICATION forming-part of Letters Patent No. 721,957, dated. March 3, 1903.

Application filed July 8, 1901. Serial No. 67,429. (No specimens.)

1'0 all whom it may concern:

Be it known that I, CHARLES A. KUENZEL, Jr., a citizen of the United States, residing in Hoboken, in the county of Hudson, State of New Jersey, have invented a new and useful Improvement in Processes of Producing Oombustible Fluids, which improvement is fully set forth in the following specification.

My invention consists of a novel method of producing a combustible fluid which is adapted to be used for lighting, heating, and such other purposes as may be expedient, provision being made for creating said fluid in a cheap, expeditious, and effective manner, it being understood that the process hereinafter described and claimed may be effected in any suitable form of apparatus, although I have shown herein one form which may be employed. Y

Figure 1 represents a diagrammatic view, partly in section, showing one form of apparatus in which .my novel process may be ef- -fected. Fig. 2 represents a section on line X X, Fig. 1, showing a plan view of one form of furnace in which the fluid generated by my invention may be utilized. Fig. 3 represents, on an enlarged scale, a sectional view, partly in elevation, of the oil-tank and'its adjuncts seen at the right of Fig. 1. Fig. 4 represents, on an enlarged scale, a plan view of one set of pipes and their adjuncts seen in Fig. 2. Fig. 5 represents a section on line Y Y, Fig. 4. Fig. 6 represents a side elevation of'Fig. 4. Fig. 7 represents, on an enlarged scale, a section on line W W, Fig. 2. Fig. 8 represents a perspective view'of a modified construction of grate which may be employed, if desired, to utilize the fluid produced by my novel process. Fig. 9 represents a sect-ion on line Z Z, Fig. 8.

Similar numerals of reference indicate corresponding parts in the drawings. I

Referring to the drawings, 1 designates an air-compressor, which same may be operated from any suitable source of power, having the air-compression cylinder 2, which is provided with a suction-pipe 3, and the air-discharge pipe 4, which leads to the tank 5, into which the compressed air is received, said tank having the outlet-pipe 6 leading therefrom to the branches 7 and 8, the latter being provided with the valve 9, said pipe 8 leading to the coil 10, which is contained within the receptacle 11, which is supplied with cold water 12 from the pipe 13, said receptacle 11 being provided with the overflow or discharge pipe 14.

15 designates a pipe leading from the coil 10 to the storage-tank 16 for compressed air, it being of course understood that the air which is initially compressed in the tank 5 is considerably heated; but by its passage through the coil 10, which is surrounded by the cold water, it will be evident that the temperature of the compressed air when the latter reaches the storage-tank 16 is considerably lowered to the requisite or working temperature.

17 designates an outlet-pipe leading from the storage-tank 16 and provided with the valve 18, said pipe 17 leading to the pipe 19, which discharges into the chamber 20 in the fitting 21, which is suitably secured to the oil-tank 22, within which is contained the oil 23 to about the level indicated in Fig. 1, it being noted that the compressed air which enters the chamber 20 is discharged in the direction of the arrows into the upper portion of the oil-tank 22, such air having been cooled sufficiently to prevent undue heating of the oil.

24 designates a discharge-pipe for the oil, the lower extremity of said pipe terminating near the bottom of the tank 22 and being provided with the perforated base 25, through which the oil can pass upwardly through the pipe 24, which is provided with the valve 26, it being noted that the upper portion of said pipe 24 passes through the packing or stuffing box 27 of the fitting 21.

28 designates a pipe in communication with the pipe 24, said pipe 28 being provided with the valve connections or fittings 29, from each of which leads a pipe 30, it being noted that each of the pipes 30 discharges into one of the mixers 31, the latterconsisting of an outer shell or casing having the reduced inlet-port 32, as will be best understood from Fig. 7, said port discharging into the annular channel 33 around the inner air-chamber 34, the latter havingthe ports 35 leading thereinto from said chamber 33.

36 designates a pipe leading from the pipe 6 for compressed air down to the pipe 37,

from which lead the pipes 38 to the cap-piece 39 of each of the mixers 31, it being understood that said pipe 37 is provided with the valve 40 and that the pipes 30 are each provided with a valve 41, whereby the flow of oil to said mixers 31 can be controlled according to requirements.

It will thus be seen from the foregoing that thechamber34serves asacommingling-chamber, wherein the oil is received in finely-divided streams through the ports 35 and is commingled with compressed air of a relatively high temperature taken directly from the tank 5 through the pipes 6 and 36 and thence by the pipes 37 and 38, the latter being controlled by the valves 42.

43 designates a pipe secured to a mixer 31 and surrounding the pipe 44 of reduced diameter, which leads from the comminglingchamber 34, it being understood that said pipe 44 projectsa shortdistance into the pipe 43 and discharges thereinto, as seen in Fig. 7. The pipes 43 lead to the branches 45, 46, 47, 48, and 49, from each of which branches, as best seen in the enlarged figure in Fig. 4, project laterally the perforated burnerpipes 50, which may be supported upon a bed or grate of refractory material 5] which may be provided with the channels 52, as will be understood from Figs. 4 and 5.

It will be apparent that in some instances, if desired, I may conduct the combustible fluid produced by my process into the pipe 53, which discharges into the upper and lower perforated loops or branches 54 and 55, the latter being preferably arranged in staggered order,as will be understood from Figs.8 and 9.

56 designates an auxiliary pump adapted to be operated by the hand-wheel 57, as seen at the right of Fig. 1, said pump being adapted to force air through the pipe 58 into the pipe 19, which discharges into the fitting 21, as already explained, it being understood that said pump 56 is employed for starting the apparatus.

The operation is as follows: The tank 5 receives the compressed air initially at a high temperature. A portion of said air is cooled or reduced to a proper working temperature and is received in the storage-tank 16, from The utilization of the combustible fluid in the furnace or grate (seen in Figs. 2, 5, and 6 or in Figs. 8 and 9) are intended merely as examples of the various uses to which the combustible fluid produced by my invention may be put.

I have found in carrying out my process that the temperature of the air from the storage-tank 5 is about 285 Fahrenheit and that the temperature of the cold air as it enters the oil-tank 22 is about Fahrenheit, although in carrying out my process I am not limited to the degrees of temperature above stated.

It will be understood that I employ compressed air of a low temperature to force the oil from the tank 22, as it exerts a greater pressure on the oil and prevents boiling and foaming of the latter in said tank, while compressed air of high temperature is directed into the mixing-chamber 34, whereby there is an effective vaporization of the oil.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

The process of producing a combustible fluid, which consists first, in compressing air, I

second, reducing the temperature of a portion ofsaid compressed air, utilizing the same to force oil into a com mingling-chamber, and lastly, commingling with said oil another portion of said compressed air of a high temperature.
